ISO 19650-1: Concepts and Principles
The fundamental framework for information management across the entire lifecycle of built assets. Part 1 of the ISO 19650 standard defines the common language, essential concepts and principles underlying the entire series.
Standard Data
About ISO 19650-1
ISO 19650-1 is the first and most fundamental part of the ISO 19650 series. Published in 2018 by the International Organization for Standardization, it defines the concepts and principles for information management throughout the entire lifecycle of built assets, using Building Information Modelling (BIM).
The standard builds on the experience gained from the British standards BS 1192:2007 and PAS 1192-2:2013, extending and internationalizing these proven principles for global adoption. It represents a convergence point of best practices from the construction industry worldwide.
ISO 19650-1 is not an operational standard — it does not prescribe exactly how each task must be executed. Instead, it establishes why and what needs to be achieved, giving organizations flexibility to choose how they implement these principles. The other parts of the series (ISO 19650-2, -3, -4, -5) provide operational details specific to each phase and domain.
In Romania, ISO 19650-1 has been adopted as a national standard under the name SR EN ISO 19650-1, published by ASRO (Romanian Standards Association).
Standard Structure
ISO 19650-1 is structured into 6 main chapters and 2 annexes, each with a well-defined role within the document:
Scope, References, Terms
The scope of the standard, normative references and definitions of key terms used throughout the document.
Information Management Concepts
Defines the fundamental concepts: CDE, information container, Project Information Model (PIM) and Asset Information Model (AIM).
Information Management Principles
The principles governing how information must be created, managed and delivered: clarity, coordination, security, accessibility.
Information Management Process
The complete flow from needs assessment to information model delivery, including iterative cycles of collaborative production.
Principles Matrix
Normative table correlating information management principles with specific activities of the delivery process.
Illustrative Example
Informative case study demonstrating the practical application of the principles and processes defined in the standard.
Information Requirements
ISO 19650-1 introduces a hierarchy of information requirements that ensures the right information is delivered at the right time, in the right format, by the responsible person. The four types are interconnected and successively derived:
Organizational Information Requirements
The information an organization needs to achieve its strategic objectives and manage assets long-term. Defined by the owner or investor at the strategic level.
Examples:
- Strategic real estate development plans
- Data for asset portfolio management
- Information for financial reporting
- Data for legal and regulatory compliance
Asset Information Requirements
The information needed for operating, maintaining and managing an asset throughout its life. Derived from OIR and specific to each built asset.
Examples:
- Equipment technical specifications
- Maintenance and intervention plans
- Warranty and certification documents
- Operating and energy consumption data
Project Information Requirements
The information needed for the successful delivery of the construction project. Defines what must be produced during the design and construction phase.
Examples:
- Architectural and structural BIM models
- Design documentation and permits
- Coordination and clash detection reports
- Execution plans and cost estimates
Exchange Information Requirements
The information that must be delivered at each information exchange point in the project. Specific as to format, level of detail and delivery time.
Examples:
- Accepted file formats (IFC, PDF, DWG)
- Level of Information (LOI) for each phase
- Applicable naming convention
- Delivery deadlines and responsible parties
The CDE Concept according to ISO 19650-1
Official ISO 19650-1 Definition
"Agreed source of information for any given project or asset, for collecting, managing and disseminating each information container through a managed process."
— ISO 19650-1:2018, Clause 3.3.15
The Common Data Environment is not just a simple cloud storage space. According to the ISO 19650-1 definition, the CDE is a governed digital environment that ensures all project information is collected, managed and distributed according to clear and traceable processes.
The 4 Information States in CDE
Work in Progress
Shared
Published
Archived
Work in Progress
Active work area for authors. Accessible exclusively to the team creating and modifying information. No other party has access in this state.
Shared
Information is shared with other teams for coordination and verification. Available for inter-disciplinary feedback, but not for final use.
Published
Information has been approved and authorized for use. Represents the official version of information, accessible to all authorized parties.
Archived
Information is permanently stored for historical reference and legal compliance. Immutable — cannot be modified after archiving.
Key Roles ISO 19650-1
ISO 19650-1 defines a clear structure of responsibilities for information management. Each role has well-defined attributes and precise hierarchical relationships:
Appointing Party
Appointing Party
Establishes information requirements (EIR) and evaluates team capabilities. Represents the client or beneficiary who engages the delivery team.
Investor, contracting authority, project manager
Lead Appointed Party
Lead Appointed Party
Coordinates information delivery from all task teams. Develops the BEP, administers the CDE and ensures compliance with EIR.
General contractor, lead designer
Appointed Party
Appointed Party
Delivers information compliant with EIR within a work package. May also coordinate sub-contracted task teams.
Sub-contractor, specialist consultant, specialty designer
Task Team
Task Team
Creates information in the WIP area. Executes individual information production tasks according to the TIDP plan.
Architectural designer, structural engineer, MEP designer
Role Hierarchy
| ISO 19650 Role | Creates requirements | Manages CDE | Produces information |
|---|---|---|---|
| Appointing Party | — | — | |
| Lead Appointed Party | |||
| Appointed Party | — | — | |
| Task Team | — | — |
Information Delivery Cycle
ISO 19650-1 describes an iterative information delivery cycle that begins with information needs assessment and ends with formal delivery of the information model. Each stage has well-defined inputs and outputs:
Assessment & Need
The client analyzes organizational needs and defines OIR. Strategic project objectives are established.
Invitation to Tender
Tender documents are prepared including detailed EIR. Pre-BEP is requested from tenderers.
Tender Response
Potential teams submit Pre-BEP demonstrating BIM capability and understanding of EIR requirements.
Appointment
Selection and contracting of the delivery team. Post-contract BEP and collaboration protocols are finalized.
Mobilization
CDE configuration, naming convention definition, workflow setup and team training.
Collaborative Production
Iterative cycles of information creation, verification and coordination through CDE according to defined states.
Information Model Delivery
Formal delivery of the Project Information Model (PIM) to the client, after verification and approval.
Project Close
Information archiving, PIM to AIM transfer and documenting lessons learned for future projects.
